The nickel-plated brass valve body and PTFE seating provide corrosion resistance and long-term sealing performance. Factory-fitted with a spring return actuator, the assembly ensures automatic fail-safe positioning during power loss and supports a wide AC/DC voltage range for simplified electrical integration. This valve-actuator combination is commonly used in heating and cooling systems requiring reliable changeover or diverting flow control. Key Features 3-Way Ball Valve Configuration: Supports both changeover and diverting flow patterns, allowing flexible hydronic system design. Spring Return Fail-Safe Actuator: Automatically drives the valve to a predefined safety position upon power interruption. Wide Voltage Compatibility: Operates on AC 24–240 V and DC 24–125 V, reducing the need for multiple actuator variants. Cv 57 Flow Capacity: Provides efficient flow handling for 1.5-inch piping while maintaining stable control characteristics. Zero Leakage Performance: Ensures tight shutoff to improve system efficiency and prevent unwanted bypass flow. Dual SPDT Auxiliary Switches: Enable precise position indication, interlocking, and system feedback functions. Manual Override Capability: Includes a hex crank for manual positioning during commissioning or maintenance activities. The B340L+AFRXUP-S delivers the reliability and precision required for safe and consistent 3-way hydronic flow control in commercial HVAC applications.
